Abstract
A method for classifying patent includes obtaining a patent abstract, carrying out judgment word treatment on said abstract, filtering word with no relation to topic in said abstract out, carrying out stem normalization treatment on filtered word, calculating weight of each word, classifying said patent and demonstrating classification result of patent.
Description
Technical field
The present invention relates to a kind of sorting technique, especially relate to a kind of patent classification method
Background technology
Frequent along with science and technology development and business activity, protection of Intellectual Property Rights is more and more paid attention to by people, and patent is exactly one of most important means in the intellecture property.Because most of new technologies all are the form appearance with patent when starting to walk, thereby have stored a large amount of technical information in patent database.Utilize these patent databases can understand the state-of-the-art technology of every profession and trade, avoid overlapping development and generation tortious, can analyze rival's technological development situation and strategy, can also analyze the development of whole industry etc.Nowadays, all open its patent database in world many countries and area, as United States Patent (USP) trademark office (United States Patent and Trademark Office) patent database, EUROPEAN PATENT OFFICE (European Patent Office) patent database, China national Department of Intellectual Property (State Intellectual Property Office of China) patent database etc.
Yet patent research is the time-consuming work of effort again, because not all patent all has researching value.How obtaining the patent information useful to company from numerous numerous and jumbled patents, how the patent information that finds is made further statistics and technical Analysis, is a great problem in the patent research.So a kind of patent classification system and method need be provided, and it utilizes patent content with patent automatic classifying, and can show the patent classification result.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of patent classification method, and it can finish the classification of patent automatically.
In order to achieve the above object, said method comprising the steps of:
(1) obtaining of patent is used to obtain the specification digest of one piece of patent;
(2) the disconnected speech of patent is used for the described specification digest speech that breaks is handled;
(3) filtering module of irrelevant speech, the speech that is used for haveing nothing to do with theme in the described specification digest filters;
(4) normalization of stem is used for that the speech after filtering is carried out stem normalization and handles;
(5) calculating of weight is used to calculate the weight of each speech;
(6) classification of patent is used for described patent classification;
(7) displaying of patent is used to show the patent classification result.
Utilize the present invention, can finish the classification of patent automatically, and show the patent classification result.
Description of drawings
Fig. 1 is hardware structure figure of the present invention.
Fig. 2 is an operation process chart of the present invention.
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, hardware configuration of the present invention comprises: application server 1, client computer 2, database 3, described client computer 2 links to each other with the described server 1 of application by network, network can be an intranet (Intranet), also can be internet (Internet) or other type communication network, described application server 1 links to each other with database 3 by data line, and application server 1 is used for patent is classified.Patent in the patent of present embodiment refers in a certain theme, described client computer 2 is used to show the patent classification result, described database 3 is used to store patent information and patent classification result.Above-mentioned patent information refers to the full detail of the patent of open or bulletin, comprises claims, instructions, and, specification digest, Figure of abstract, applicant, the applying date, patentee etc.
As shown in Figure 2, the invention provides a kind of patent classification method, this method may further comprise the steps:
(1) obtaining of patent is used to obtain the specification digest of one piece of patent, and the user realizes on client computer 2;
(2) the disconnected speech of patent is used for the described specification digest speech that breaks is handled, and promptly according to space or punctuation mark sentence is divided into speech, realizes by application server 1 accessing database 3;
(3) filtering module of irrelevant speech, the speech that is used for haveing nothing to do with theme in the described specification digest filters, and realizes by application server 1 accessing database 3;
(4) normalization of stem is used for that the speech after filtering is carried out stem normalization and handles, and the different shape that is about to same speech is normalized to same form, realizes by application server 1 accessing database 3;
(5) calculating of weight is used for according to each speech calculating the weight of this speech in this patent in the frequency that this specification digest occurs, and realizes by application server 1 accessing database 3;
(6) classification of patent is used for the result of described patent classification according to weight calculation classified above-mentioned patent;
(7) displaying of patent is used for the patent classification result is illustrated on the client computer 2.
Claims (1)
1. patent classification method is characterized in that said method comprising the steps of:
(1) obtaining of patent is used to obtain the specification digest of one piece of patent;
(2) the disconnected speech of patent is used for the described specification digest speech that breaks is handled;
(3) filtering module of irrelevant speech, the speech that is used for haveing nothing to do with theme in the described specification digest filters;
(4) normalization of stem is used for that the speech after filtering is carried out stem normalization and handles;
(5) calculating of weight is used to calculate the weight of each speech;
